* The ClassLoader is a way of customizing the way Java gets its classes
|
|
|
|
* and loads them into memory. The verifier and other standard Java things
|
|
|
|
* still run, but the ClassLoader is allowed great flexibility in determining
|
|
|
|
* where to get the classfiles and when to load and resolve them. For that
|
|
|
|
* matter, a custom ClassLoader can perform on-the-fly code generation or
|
|
|
|
* modification!

2002-12-09 01:04:00 +01:00

|
|
|
* <p>The grandparent of all classloaders is the bootstrap classloader, which
|
|
|
|
* loads all the standard system classes as implemented by GNU Classpath. The
|
|
|
|
* other special classloader is the system classloader (also called
|
|
|
|
* application classloader) that loads all classes from the CLASSPATH
|
|
|
|
* (<code>java.class.path</code> system property). The system classloader
|
|
|
|
* is responsible for finding the application classes from the classpath,
|
|
|
|
* and delegates all requests for the standard library classes to its parent
|
|
|
|
* the bootstrap classloader. Most programs will load all their classes
|
|
|
|
* through the system classloaders.
|
|
|
|
*
|
|
|
|
* <p>The bootstrap classloader in GNU Classpath is implemented as a couple of
|
|
|
|
* static (native) methods on the package private class
|
|
|
|
* <code>java.lang.VMClassLoader</code>, the system classloader is an
|
|
|
|
* instance of <code>gnu.java.lang.SystemClassLoader</code>
|
|
|
|
* (which is a subclass of <code>java.net.URLClassLoader</code>).
|
|
|
|
*
|
|
|
|
* <p>Users of a <code>ClassLoader</code> will normally just use the methods
|
|
|
|
* <ul>
|
|
|
|
* <li> <code>loadClass()</code> to load a class.</li>
|
|
|
|
* <li> <code>getResource()</code> or <code>getResourceAsStream()</code>
|
|
|
|
* to access a resource.</li>
|
|
|
|
* <li> <code>getResources()</code> to get an Enumeration of URLs to all
|
|
|
|
* the resources provided by the classloader and its parents with the
|
|
|
|
* same name.</li>
|
|
|
|
* </ul>
|
|
|
|
*
|
|
|
|
* <p>Subclasses should implement the methods
|
|
|
|
* <ul>
|
|
|
|
* <li> <code>findClass()</code> which is called by <code>loadClass()</code>
|
|
|
|
* when the parent classloader cannot provide a named class.</li>
|
|
|
|
* <li> <code>findResource()</code> which is called by
|
|
|
|
* <code>getResource()</code> when the parent classloader cannot provide
|
|
|
|
* a named resource.</li>
|
|
|
|
* <li> <code>findResources()</code> which is called by
|
|
|
|
* <code>getResource()</code> to combine all the resources with the
|
|
|
|
* same name from the classloader and its parents.</li>
|
|
|
|
* <li> <code>findLibrary()</code> which is called by
|
|
|
|
* <code>Runtime.loadLibrary()</code> when a class defined by the
|
